Ezweni elibaluleke kakhulu lokukhiqiza ngokunemba, ukwethembana akusekelwe kuma-algorithm esofthiwe kuphela—kusekelwe ku-physics. Kungakhathaliseki ukuthi usebenzisa umshini wokulinganisa ohlanganisayo (i-CMM) ukuqinisekisa ama-turbine blades e-aerospace noma isithwebuli se-3D esinesinqumo esiphezulu ukuze ushintshe izingxenye zezimoto ezindala, ubuqotho bezilinganiso zakho abuqali nge-probe noma i-laser, kodwa ngalokho okungaphansi: isisekelo somshini. Kwa-ZHHIMG, besilokhu sikholelwa ukuthi akukho simiso se-metrology esingadlula isisekelo saso. Futhi uma kukhulunywa ngokuletha ukunemba kweqiniso nokuphindaphindekayo—ikakhulukazi ezindaweni zezimboni ezishintshashintshayo—kukhona into eyodwa kuphela ehlangabezana nezidingo zezinhlelo zokukhanya nezokuthinta: i-precision granite.
I-granite ayiyona nje yendabuko; ingcono kakhulu ngokwezibalo. Ngokungafani nezisekelo zensimbi noma ze-polymer ezihlanganisiwe ezikhula, zinciphe, noma zizwakale ngaphansi kokucindezeleka kokushisa noma komshini, i-granite yemvelo inikeza ukwanda kokushisa okucishe kube yi-zero, ukudambisa ukudlidliza okumangalisayo, kanye nokuqina kobukhulu besikhathi eside. Lezi akuzona izimangalo zokumaketha—ziyizakhiwo zomzimba ezisekelwe ku-geology. Ukuze kulinganiswe ngokulinganisela.isisekelo somshini we-granite womshini, lokhu kusho ukuthi indiza yokubhekisela lapho kwenziwa khona zonke izilinganiso ihlala ingashintshi phakathi nokushintshashintsha, izinkathi zonyaka, ngisho namashumi eminyaka okusetshenziswa.
Kodwa kungani lokhu kubaluleke kakhulu kunanini ngaphambili namuhla? Ngoba i-metrology yanamuhla iyahlangana. Umugqa phakathi kwama-CMM athintekayo kanye nama-scanner e-3D angathintani uyafiphala. Izinhlelo ze-hybrid manje zihlanganisa ama-probe e-touch-trigger nama-scanner okukhanya noma e-laser ahlelekile ukuze abambe ama-datum e-geometric kanye nezindawo eziyinkimbinkimbi ze-freeform kusethi eyodwa. Kodwa lokhu kuhlanganiswa kwethula izinselelo ezintsha: izinzwa ze-optical zizwela kakhulu ekudlidlizeni okuncane kanye nokushushuluza kokushisa. Isisekelo "esizizwa" sizinzile emehlweni omuntu singase sethule i-jitter eyanele yokufiphala idatha yokuskena noma ukushintsha amafu amaphoyinti ngama-micron amaningana—okwanele ukuvimbela ama-callout aqinile e-GD&T.
Yilapho i-granite enembile yamapulatifomu esikena se-3D ingaba khona lapho kungaxoxiswana khona. Kwa-ZHHIMG, asifaki kabusha ama-slab ajwayelekile.isisekelo se-graniteIzinhlelo zokuskena ze-optical zakhiwe nge-diabase ethambile, enezimbobo ezincane ezitholakala ezinkwalini eziqinisekisiwe eScandinavia naseNyakatho Melika—ezikhethwe ngokukhethekile ukuze kube nokuvumelana kobuningi kanye nokulingana kwangaphakathi. Lawa mabhulokhi adlula ukuguga kwemvelo izinyanga eziyi-12-24 ngaphambi kokuba alingane ngokunemba kuze kube yilapho ebekezelela ukuthamba ngaphakathi kwama-micron angu-2-3 ngaphezu kwebanga elingaphezu kwamamitha ama-3. Kulapho kuphela lapho kuhlanganiswa khona izixhumi zokufaka, izindawo zokubeka phansi, kanye neziteshi zokuphatha ikhebula—ngaphandle kokubeka engcupheni ukuqhubeka kwesakhiwo setshe.
Umphumela? Ipulatifomu ezinzile kangangokuthi ngisho nezinzwa zokufuduka ze-sub-micron zibhalisa ukugeleza okuncane ngesikhathi sokukhiqizwa kwamahora angu-8. Omunye wamakhasimende ethu aseYurophu emkhakheni wamathuluzi we-semiconductor muva nje ufake itafula le-optical le-carbon-fiber ngesisekelo se-granite se-ZHHIMG sesithwebuli sabo sokukhanya okuluhlaza okwesibhakabhaka esisheshayo. Umphumela? Ukuphindaphindwa kokuskena kuthuthuke kusuka ku-±8 µm kuya ku-±2.1 µm—hhayi ngoba isithwebuli sishintshile, kodwa ngoba isisekelo siyeke “ukuphefumula” ngokushintshashintsha kwezinga lokushisa elizungezile.
Futhi akukhona nje kuphela ngama-scanner. Ezimbonini ezithembele kumathuluzi okulinganisa avundlile—njenge-CMM yengalo evundlile esetshenziswa ekuhlolweni komzimba okumhlophe kwezimoto noma i-metrology enkulu yama-valve kawoyela negesi—izidingo ezisesisekelweni zinzima kakhulu. Izakhiwo ezivundlile ngokwemvelo zidala imithwalo evundlile ekhulisa noma yikuphi ukuguquguquka kwesakhiwo sokusekela. I-weldment yensimbi ingaphambuka ngokubonakalayo ngaphansi kwamandla e-probe; ngisho nezitezi zekhonkrithi eziqinisiwe zingadlulisela ukudlidliza kwesakhiwo. I-granite, enamandla ayo aphezulu okucindezela (ngokuvamile >250 MPa) kanye nesilinganiso sokunciphisa sangaphakathi esingu-3–5× kangcono kunensimbi ephonswe, iqeda le miphumela emthonjeni.
Yingakho sithuthukise i-granite eqondile ekhethekile yezinsimbi zokulinganisa ezivundlile ezidlula ukuba yisicaba. Izisekelo zethu zezingalo ezivundlile zinezikhonkwane ze-kinematic ezihlanganisiwe, ama-datum rails aqondaniswe kahle, kanye nokuvikela ukushisa okuzenzakalelayo—konke kulinganiswe nezindinganiso ze-ISO 10360. Esifundweni sokuqinisekisa sakamuva nomhlinzeki wezimoto we-Tier-1, i-i-CMM evundlile esekelwe ku-graniteigcine ukunemba kwevolumu okungu-±(2.8 + L/250) µm kuyo yonke imvilophu yamamitha ayi-6, yenza kahle kakhulu kunesistimu enohlaka lwensimbi encintisanayo ngo-37% ezivivinyweni zokuphindaphinda zesikhathi eside.
Ngokugxekayo, i-ZHHIMG iphatha yonke ipulatifomu ye-metrology njengohlelo oluphelele—hhayi iqoqo lezingxenye. Isisekelo somshini we-granite womshini wokulinganisa ama-coordinate asiyona into ecatshangelwe kamuva eboshelwe kufreyimu; yifreyimu. Zonke izindlela zokuqondisa, ama-bearings, kanye nezikali ze-encoder zibhekiselwa ngqo ebusweni be-granite ngesikhathi sokuhlanganiswa kokugcina, zisusa amaphutha aqongelelekayo avela ezingqimbeni zokufaka eziphakathi. Le ndlela inciphisa isikhathi sokusetha, yenza kube lula ukulinganisa, futhi—okubaluleke kakhulu—iqinisekisa ukuthi idatha ethintekayo neyokukhanya ihlala endaweni efanayo yangempela yokuhlanganisa ama-coordinate.
Siphinde senqabe izindlela ezinqamulelayo. Abanye abakhiqizi basebenzisa amatshe aphinde ahlanganiswa noma ama-epoxy-granite ukuze banciphise izindleko nesisindo. Nakuba kwamukelekile ekusetshenzisweni okulula, lezi zinhlanganisela azinawo ukuqina kwesikhathi eside okudingekayo ku-metrology eqinisekisiwe. Kwa-ZHHIMG, zonke izisekelo zithunyelwa ngesitifiketi esiphelele sezinto—kufaka phakathi ubuningi, i-porosity, i-thermal expansion coefficient, kanye namamephu e-flatness—ngakho onjiniyela bekhwalithi bangaqinisekisa ukulandelelwa kwezindinganiso zomhlaba wonke.
Ukuzibophezela kwethu kusitholele idumela elithule phakathi kwabaholi kwezokuhamba ngezindiza, ukukhiqizwa kwamadivayisi ezokwelapha, kanye nokukhiqizwa kwezimoto zikagesi. Umkhiqizi webhethri le-EV wase-US muva nje uthumele iziteshi ze-ZHHIMG granite hybrid ezihlanganisa ama-touch probe kanye nezikena ze-3D ukuhlola ukuhambisana kwamaseli kuma-gigafactory. Ngokunamathisela zombili izinhlobo zezinzwa ku-datum efanayo ye-granite engasebenzisi ukushisa, bathole ukuhlangana kokuqinisekiswa okuphakathi kwama-µm angu-3—into eyayibhekwa njengengenakwenzeka ngaphambili ematafuleni ahlanganisiwe.
Ngaphezu kwalokho, ukusimama kwakhelwe kule filosofi. I-granite ingokwemvelo ngo-100%, ingaphinde isetshenziswe ngokugcwele, futhi ayidingi ukumbozwa noma ukulungiswa ngaphandle kokuhlanzwa okuvamile. Ngokungafani nohlaka lwensimbi olupendiwe oluqhekeka noma olubolayo, i-granite enakekelwa kahleisisekelo se-graniteempeleni iyathuthuka ngokuguga, ithuthukise indawo ebushelelezi ngokusetshenziswa ngobumnene. Ukufakwa kwethu okuningi kusukela ekuqaleni kwawo-2000 kusasebenza nsuku zonke ngaphandle kokonakala kokusebenza—ubufakazi benani elihlala njalo lento.
Ngakho-ke njengoba uhlola ukutshalwa kwezimali kwakho okulandelayo kwe-metrology, zibuze: ingabe uhlelo lwakho lwamanje lusekelwe esisekelweni esenzelwe iqiniso—noma ukulula? Uma ukuskena kwakho kwe-3D kubonisa umsindo ongachazeki, uma i-CMM yakho idinga ukulinganiswa kabusha njalo, noma uma isabelomali sakho sokungaqiniseki kokulinganisa siqhubeka sikhula, imbangela ingase ingabi sezinzwa zakho, kodwa kulokho ezikusekelayo.
Kwa-ZHHIMG, simema ochwepheshe be-metrology kulo lonke elaseNyakatho Melika, eYurophu, nase-Asia-Pacific ukuze babone umehluko owenziwa yisisekelo sangempela se-granite.www.zhhimg.comukuhlola izifundo zamacala zangempela, ukulanda amaphepha amhlophe obuchwepheshe mayelana nezindlela zokukhetha i-granite, noma ukuhlela ukuboniswa bukhoma kwamapulatifomu ethu ahlanganisiwe. Ngoba ekulinganisweni okunembile, azikho izinkolelo-mbono—kuphela isisekelo esiqinile.
